Frequently Asked Questions
- Can I blur sensitive information in screenshots?
- Yes. Select the blur or pixelate tool, then draw over the area you want to hide. The blur effect is applied permanently when you export, so the original content cannot be recovered.
- What annotation tools are available?
- Pen (freehand drawing), marker (semi-transparent highlight), arrows (pointing to areas), boxes (rectangular outlines), blur (gaussian blur), and pixelate (mosaic effect). Each has 10 color options.
- Can I undo mistakes?
- Yes. Use Ctrl+Z to undo and Ctrl+Shift+Z to redo. You can undo multiple steps back to the original image.
